Hello Dan,
Thanks for the notes on the wiki. That is a useful step forward.
Just a few additional thoughts for discussion...
As concerns the background section, you are mentioning the BBC programme ontology, EBU (actually the Class Conceptual Data Model - CCDM) and TV-Anytime. These three initiatives have in common to address the distribution model of content. The models, sometimes with slightly different names, define what a service (broadcast, VoD, Ctach-up TV or else) is. In the case of e.g. broadcast is leads to the definition of a channel described by a scheduled and broadcast events (schedules or not) associated to programmes (or versions of a programme). This is also true for VoD/catch-up TV objects , etc.
Why would it make sense to address the above in the model? Because content is always available in these contexts. Even if content could be found directly, linking it more clearly to its source would allow to exploit this additional information and find the same content using extended search criteria (e.g. what is now on what channel/web service, etc.).
Another source of initial improvement for the ontology could be to consider collections at large (a catch-up TV offer can be treated as a collection) and not restrict ourselves to serial, series or seasons.
All the best, Jean-Pierre
PS: I am not sure I actually am on the reflector. I'll try to sort this out. If not, feek free to forward this on my behalf. Thanks.

Subject: Schema.org TV vocabulary - opening discussion
A few of us have been discussing informally some possibilities for
improving Schema.org's description of TV.
I have put some notes in our Wiki at http://www.w3.org/wiki/SchemaDotOrgTV
Excerpting briefly,
"'"At launch, Schema.org contained basic vocabulary for describing
TV-related entities.
TVEpisode: director, actors, producer, trailer, productionCompany,
partOfTVSeries, partOfSeason, episodeNumber, musicBy
TVSeason: trailer, episodes, partOfTVSeries, seasonNumber,
numberOfEpisodes, startDate, endDate
TVSeries: director, actors, producer, trailer, productionCompany,
episodes, seasons, numberOfEpisodes, musicBy, startDate, endDate
Movie: duration, director, actors, producer, trailer, productionCompany, musicBy
This captures a lot of existing structured data available in the
consumer-facing Web. However it is missing some pieces that are
already available in structured data form."""
This is a good start, but there are various other things to be said
about TV episodes, series/seasons (plus some internationalisation
issues on terminology). Talking with Jean-Pierre and Yves confirms my
suspicion that there is useful work to be done here.
The Wiki does not capture the entire picture but hopefully is enough
to get discussions started. For example, how best to describe
broadcasts, availabilities, segments/tracklists; where we want to keep
track not only of when something is available, but also the
country/territory in which it is being made available. This is a very
common situation in online TV, since broadcast rights are partitioned
by geography, even while the metadata is available globally...
cheers,
Dan
